Im planning on cycling to Brighton and back in a few weeks, but my bike is still having a lot of teething problems. It is now in an unridable state (this is not up for discussion) and i would like to get it repaired at 'onyourbike' in london bridge. Im based in canons park and commute to london bridge on the jubilee line daily, however i am told i cant take the bike with me as its a deep underground station. What are my options? can i take a wheel off and go on the tube....I carried home a huge box with a bike stand during rush hour and there were no quibbles, any opinions?
